Entering feed prices using the Guaranteed feed list:
Entering feed prices can be done in several ways. Select the feed list you want to change. Select the tab "Feed prices". Double-click the cells and edit the feed price. Finish each cell by pressing "Enter".
Note that there are no prices in the national guarantee list and no prices can be entered into that feed list. Use your stable feed list for the purpose, or create new separate feed list to distribute prices.
You may also edit individual feeds in all other feed lists. You will have to update these manually.
A final possibility is to edit the feed prices directly in the ration of individual horses. When this is done, PC-Horse asks whether the changes should be copied across to all horses in the stable.
